MAX OTTO CLAUSS, OF NEW YORK, N. Y.

TUBULAR-BAND-IVIAKING MACHINE.

Application filed May 25, 1921, Serial No. 472,533. Renewed October 20, 1923.

To all whom it may concern:

Be it known that I, MAX OTTO CLAUss, a citizen of the United States, and resident of the borough of the Bronx, in the county of the Bronx and the city and State of New York, have invented certain new and useful Improvements in Tubular-Band- Making Machines, of which the following is a specification.

This invention relates to tubular band making machines and has for its primary object to provide a mechanism capable of very high speed operation for automatically forming from sheets of paper or other material of requisite length and width, tubular bands to be used for binding the strands of thread skeins or for various other analogous purposes.

In one embodiment of the invention I provide a hollow suction bar movable towards and from a magazine in which the paper sheets are contained and around which the tubular band is formed, means for applying an adhesive to one end of the paper sheet and for bending the end portions in overlapping relation upon each other, means for removing the formed band from the suction bar, and a single operating shaft provided with means for actuating the several relatively movable parts of the mechanism in properly timed relation to each other.

It is a. more particular object of the invention to provide an arrangement of cams fixed upon the common operating shaft for actuating the several relatively movable parts of the mechanism.

It is further a detail object of the invention to provide simple and effective means for assuring the stripping or removal of the formed band from the suction bar without tearing or injuring the band.

WVith the above and other objects in view, the invention consists in the improved form, construction and relative arrangements of the several parts as will be hereinafter more fully described, illustrated inthe accompanying drawings and subsequently incor porated in the subjoined claims.

In the drawings wherein similar reference characters designate corresponding parts throughout the several views,

Figure 1 is a side elevation illustrating one practical embodiment of the present invention;

Figure 2 is a top plan view;

Figure '3 is an elevation of the opposite others broken away, and

side of the Figure 1;

Figure 4 is a front end elevation, certain parts of the machine being omitted and machine to that shown in Figure 5 is a fragmentary plan view showing another position of certain of the parts.

Referring in detail to the drawings, the machine frame in which the several operating parts are mounted includes a base 5 and the side plates 6.

Upon the transverse bar 7 connecting the side plates at one of their ends, ,amagazine S is mounted. This magazine receivesthe sheets of paper or other material indicated at 9 which are urged inwardly by means of a follower 10, the projection of the paper sheets beyond the inner end of the magazine being resisted by the yieldable spring members 11 arranged at the opposite sides of the magazine chamber. The follower 10 is moved longitudinally in the magazine and exerts a constantly decreasing pressure upon the paper sheets 9 therein as the latter are successively moved through the medium of a lever 12 fulcrume d at its lower end as at 13, upon an arm 14 fixed to the machine frame. The upper end of this lever is connected by the link 15 to the follower 10.

Upon the pivot or fulcrum 13 of the lever a coil spring 16 is engaged, one end of said spring bearing against the outer edge of the lever. When the magazine 8 is supplied with the paper sheets 9, the lever 12 is rocked upon its fulcrum and the spring 16 placed under considerable tension. As these .paper sheets are successively removed from the magazine and formed into bands, the fol-lower 10 presses the remaining sheets rearwardly in the magazine and in this movement of the follower the tension of the spring 16 gradually decreases so that by the time the magazine is almost exhausted,

there. will be relatively little pressure of the follower 10 against the remaining paper sheets. Thus the holding action of the yieldable elements 11 will not be overcome and permit of the projection of the paper sheets beyond the inner end of the magazine.

In the side plates 6 of the machine frame a shaft 17 operated from any convenient source of power is journaled. A cam member 18 is fixed upon one end of this shaft exteriorly of the frame, said member having a cam track 19 to receive a stud 20 projecting from'a collar 21 fixed upon the rod 22. This rod is axially movable through the guides 23 on the frame. In order to prevent the turning or rotary movement of the rod 22, the sleeve 21 is provided with an arm 24 having an opening therein to loosely receive the guide rod 25 which is fixed at one of its ends in the bracket 26 secured to the frame plate 6 of the machine.

Upon the forward end of the rod 22, the coupling head 27 is securely fixed, as by means of the clamp 28 and has a threaded nipple 29 to receive the end of a flexible suction hose (not shown). The head 27 is longitudinally bored as at 30 and the inner end of this bore opens through one side of said head. With this open end of the bore, an opening indicated at 31 in one side of the hollow suction bar 32 is adapted to coincide, the end of the suction bar being securely fixed upon the end of the head 27 by means of the clamp plate 33. Additional spaced openings 34 extend through the relatively opposite side wall of the hollow suction bar 32. Thus when the vacuum pump or other equivalent means is operated, it will be understood that air is drawn in through the openings 34 of the bar 32 and through the bore of the head 27.

The suction bar 32 is opposed to the inner end of the magazine 8 and this bar is shifted laterally with respect to the magazine through the medium of the cam member 18 coacting with the stud 20. In the position of the stud 20 in the cam track 19 as shown in Figure 3, the rod 22 is projected forwardly to the limit of its movement and the suction bar 32 will then be disposed in contact with the first of the paper sheets 9 in the magazine. The purpose and result of such operation will be more fully expained in the subsequent description.

In the rear end of the machine frame a transversely disposed fixed shaft 35 is mounted and upon this shaft the independently operable arms 36 and 37 respectively are supported for rocking or pivotal movement. The arm 36 has a vertical rear end portion extending above the shaft 35 and a forwardly and downwardly inclined portion 38 upon the end of which a paste container or box 39 is mounted. The other lever 37 also has a vertical rear end portion extending below the shaft 35 and a forwardly extending longitudinal portion 40 upon the end of which the roller 41 is yieldably mounted, said roller being journaled be tween spaced links 42 pivoted upon the end of the arm. The arms 36 and 37 respectively extend above and below the shaft 17 in the same vertical plane. Upon each side of these arms, identical cam members 43 are fixed upon the shaft 17. Each of these members has a cam track 44. A roller 45 carried by the arm 36 is engaged in the cam track of one of the members 43 while a similar roller 46 is engaged in the cam track of the other of said members.

The rear ends of the side plate 6 of the machine frame are connected at their upper edges by the transverse bar 47 which is provided with a bearing 48 to receive the upper end of a vertically disposed rockshaft 49, the lower end of which has a bearing in the base 5 of the frame. To the upper end of said shaft an arm 50 is fixed and this arm has a universal pawl and socket connection 51 to one end of a rod 52, the other end of which has a similar pawl and socket connection 53 to the upper end of a vertically disposed lever 54 which is fulcrumed at its lower end as at 55 upon one of the side plates 6 of the frame. Upon this lever intermediate of its ends, the roller 56 is mounted for engagement in the track 57 of a cam member 58 which is fixed upon the shaft 17 To the rock shaft 49, intermediate of its ends, one end of a forwardly extending arin 59 is fixed. The other end of this arm is connected by means of the link 60 to one end of the band stripper 61 which is mounted for transverse sliding movement upon the vertically spaced rods 62 fixed at their ends in opposite sides of the machine frame. The stripper 61 as herein shown, consists of a metal plate having a longitudinally extending rectangular channel 63 in its rear face. In this channel a transversely movable bar 64 is mounted, said bar being normally urged outwardly by means of the springs 65 fixed to the front face of the stripper plate and hearing at their free ends against the pins 66 on the bar 64 which are loosely movable through spaced openings in the stripper plate. The face of the bar 64 is preferably covered with a thin sheet of rub ber or other friction material for a reason which will presently appear. The channel or groove 63 has a depth which is equivalent to the combined thickness of the bar 64 and the suction bar 32.

In the outlet of the paste box 39 at its lower end a roller 67 is mounted and on one end of the roller shaft a ratchetdisc 68 is fixed. In the downward movement of the paste box this ratchet disc is engaged by the free end of a pawl 69 pivoted as at 70 upon the machine frame whereby the paste applying roller is rotated to carry the paste from the box to the end of the paper sheet.

In the operation of the mechanism as above described, assuming that the parts are in the relative positions as shown. in Figure 2 of the drawing, upon the rotation of the operating shaft 17 the suction bar 32 is first moved forwardly through the medium of the cam members 18 as above explained, and the front side of said bar is engaged against the first of the paper adhere to the adhesive coated surface.

sheets in the magazine 8. The suction created in this hollow bar holds the paper sheet against the front face thereof so that when the bar is retracted in the continued rotation of the cam member 18, the paper sheet will be carried therewith. The stripper 61' is now moved through the connections with the cam member 58 and positioned between the magazine and the suction bar 32. The cam 18 now again advances the bar 32 having the paper sheet thereon and positions said bar in the groove or channel 63 of the stripper 61. The central portion of the paper sheet is thus moved into said groove or channel and against the bar 63, said bar being moved inwardly against the base wall of the channel against the action of the springs 65. The ends of the paper sheet project laterally from the groove 63 in parallel relation to each other. One of the cams 4:3 coacting with the roller 45 now rocks the arm 36, thereby moving the paste box 39 downwardly, in which movement the pawl 69 rotates the paste applying roller. This roller engaging the upper end portion of the paper sheet bends the same downwardly a ainst the rear side of the bar 32, at the same time applying the paste or adhesive thereto. As the paste box is returned to its former position, the arm 37 is rocked by the other of the cams 43 and the roller 11 carried thereby moved upwardly against the lower end portion of the paper sheet as seen in Figure 1 and folds said end portion inwardly into overlapping relation upon the other end portion. The roller 41 applies sufficient pressure so as to cause the end of the paper sheet engaged thereby to tightly In this manner the paper blank is automatically folded in the form of a rectangular tube around the suction bar 32.

The stripper 61 is' now withdrawn from in front of the magazine to the position shown in Figure 2 of the drawing. The bar ()4 being urged outwardly in the groove or channel 63 by the spring 65 causes the friction facing material engaging one side of the paper tube to tight-1y adhere to the tube so that the latter is withdrawn longitudinally or stripped from the bar 32, the tube falling by gravity into a suitable receptacle. The cycle of operations above described is then repeated and another tubular band is formed.

From the foregoing description considered in connection with the accompanying drawings, the construction and manner of operation of the improved band forming mechanism will be readily understood. As the several relatively movable parts are actuated from a common primary operating shaft, the machine may be operated at a very high speed and with a relatively small consumption of power. The paper bands will thereby be rapidly and accurately pro duced from the blanks at relatively small cost. It will be apparent that these bands may be made of any desired length and width as may be required in viewv of the particular purpose for which they are to be used.

While- I have herein shown and described one practical and satisfactory embodiment of the invention, the same is nevertheless susceptible of many modifications 1 in the form, construction and relative arrangement'of its several parts and I, therefore, reserve the privilege of adopting all such legitimate changes as may be clearly embodied within the spirit and scope of the invention as claimed.
